Fucking cunts are costing me money, I got multiple defective RX480 4GB cards.
At least it's defective from the beginning, and part of the VRM doesn't blow up instead bringing the whole rig down.
The image proxy of the forum hates huge threads, so I can't find the post itself, but somebody uploaded a picture of it:

The problem is the lack of at least a single reliable manufacturer. Almost every series of cards in the past few years had blowing up VRM: 7000 series Gigabytes, 300 series Sapphire, and now 400 series MSI.
